In the embodiment according to the present invention, the stock information server 100 also configures and transmits information for more effectively delivering stock information in addition to the information directly related to the stock, which is shown in FIG. Likewise, there is text information, server information and link information.

If necessary, the stock information server 100 configures and transmits the STK component 404 carrying character information in text form according to the syntax illustrated in FIG. 9N. Such text information may be stock quotes or urgent news or announcement information related to a particular item.

In addition, the stock information server 100 configures and transmits an STK component carrying server information in the case of information on a quote or item in which more detailed or professional information may be provided if necessary. Detailed or professional information about stock information may be provided from a server other than the stock information server 100. In this case, the other server may inform the stock information that may provide detailed or professional information in a manner promised to the stock information server 100, and the stock information server 100 may be added. When constructing and providing stock information capable of providing information, the STK component 405 carrying server information is transmitted. The server information may be provided even in the case of stock-related information exemplified for the description of the present invention, rather than professional information not illustrated in the description of the stock-related invention. For example, when constructing a service that provides information on indexes and stocks frequently, and provides a query or request from a terminal for graphs or charts, etc., it provides graphs and charts when providing index or stock information. It is expected to request information such as and to configure and provide STK component of server information.

The STK component of the server information is configured according to the syntax illustrated in FIG. 9O. The STK component of the server information includes a value 911 (<stk11_xx>) indicating the type of the server and a URI and a port number, which are location information for accessing the server. 912). The type of server is assigned to distinguish whether the server is a 'securities detailed information providing server' or a 'securities trading server'.

The access location information in the STK component of the server information configured and provided in this manner is used to connect with a server that is decoded by the terminal 200 to obtain detailed or professional information, and the connection at this time is The terminal 200 uses a separate bidirectional communication channel that can be used. This will be described later in detail.

On the other hand, information directly related to stocks, etc., as well as indirectly related information, such as road flooding or railroad failure due to flooding in a specific region, affects the stock price of the freight forwarding industry or transport companies. However, such a traffic disturbance, weather or climate may be provided through a TPEG message for other application information in the TPEG message sequence illustrated in FIG. 2A. Therefore, when the stock-related information currently provided is related to the transmission information of the message transmitted, transmitted or transmitted in the TPEG message of other application information, the stock information server 100 is illustrated in FIG. 9P. The STK component 406 of link information is constructed and transmitted according to the syntax. Of course, the information needed to fill the fields illustrated in FIG. 9P will be received and used from a server providing associated application information. Alternatively, the received information may be finally provided to a Carrier Server that forms and transmits a transport frame as illustrated in FIG. 11 so that the transport server may fill the fields illustrated in FIG. 9P to complete the STK component. In the description of the embodiment according to the present invention, the traffic information providing server 110 may be the transmission server.

Referring to the transmission frame illustrated in FIG. 11, the transmission server configures TPEG messages of received or generated application information into a sequence of transmission frames. Each transmission frame 1100 includes a frame start signal 1101a at its front end and a frame end signal 1101b at its rear end, and a service ID (SID) of a signal sender (in this example, the transmission server) inside the frame. 1102 is written and at the same time data of TPEG messages carrying application information is packed. At the front end of each TPEG message, a service component ID (SCID) 1103 is added to identify the type of information serviced by the data. The data block in the transport frame packed with the data of the SCID and TPEG message is called a 'service component frame'.

When there is information associated with other application information in the service component frame 1110 for stock related information to be constructed and transmitted as a transmission frame, the transmitting server may provide information about the association. Server, for example, the stock information server, a news information server, etc.), an application ID (AID) assigned to the associated application information service as shown in Fig. 11, and the application information is transported. An STK component of link information is constructed by the SCID assigned to the service component frame and the TPEG message identifier (MID) carrying the application information, and inserted into the service component frame 1110 for stock information. Or is pre-configured in the frame 1110. Fill the values in the corresponding fields (1121,1122,1123) of the STK components of the link information. The application ID is a value that is pre-assigned for each application service, which is a value that is known to a terminal designed to use the application service. For example, 04h may be allocated to the congestion information service, 0Dh may be allocated to the news service, and 0Eh may be allocated to the stock information service.

The example shown in FIG. 11 shows the structure of the link information which associates the TPEG message of the news information service which has the news content which may affect the stock price which is provided. If the terminal receiving the transmission frame configured as illustrated in FIG. 11 has the ability to decode news information in addition to the stock information, the corresponding service component with reference to the connection information contained in the STK component 1120 of the link information. The TPEG message in the frame can be found and decoded and the content of the decoded association information provided to the user in an appropriate form.

The stock information server 100 combines the STK components as illustrated in FIG. 12 to provide the user with information about the stock. The configuration of the STK component illustrated in the drawings is merely an example and is not necessarily to be combined as illustrated, and may include a new STK component in which some of the illustrated STK components are excluded or not illustrated in the TPEG message.

In the transport format illustrated in FIG. 12, the index container 1201 is configured with information according to the syntax illustrated in FIGS. 5A to 5H in the same manner as described above with reference to FIG. 6, where a value indicating the type of an index is set. A value indicating to stk02_2 that is for an individual item is displayed in the index type part 1211. Of course, the code for specifying the individual items is also contained in the index information section in the index type section 1211.

A component (STK component of identifier 80h) 1202 that carries the quote information of FIG. 12 is composed of information according to the syntax illustrated in FIGS. 5I to 5L, and FIG. 13 shows a transmission format of a component that carries the quote information configured accordingly.

The stock price component may contain information on the fluctuation, the quote, and the trading volume for the specified stock item, wherein the fluctuation information is obtained by the stock price component 1301 of identifier 00h, and the quote information is the stock price component of identifier 01h. By 1302, the transaction volume information is sent by the stock price component 1303 of identifier 02h.

The stock price component 1301 of the fluctuation information constructed in accordance with the syntax illustrated in FIG. 5J is a value (<stk06_xx>) 1312 and a lock representing a fluctuation classification according to each bit value of the selector 1311. It may optionally include a value (<stk07_xx>) 1313 indicating the division. The value representing the rise and fall (<stk06_xx>) 1312 is, for example, 0 is unknown, 1 is no transaction, 2 is the upper limit, 3 is the increase, 4 sides are the lower limit, 5 is the lower limit, 7 Is assigned as the upper limit of the force, and the like (<stk07_xx>) 1313 indicating the division of the lock is an assigned value such as 0 for unknown, 1 for normal, 2 for right lock, and 3 for dividend lock. .

The stock price component 1302 of the quote information, constructed according to the syntax illustrated in FIG. 5K, first obtains a value (<stk08_xx>) 1321 indicating a unit of number (eg, 1000, 1000000, etc.) to be transported. In addition, according to each bit value of the selector 1322, the information on the fluctuation range 1323, the current price 1324, and the high price 1325 and the low price 1326 may be selectively included. The numbers in the fields 1324, 1325 and 1326 are coded by the stock information server 100 so that the value <stk08_xx> representing the unit can be multiplied and interpreted as actual information. For example, if the present price of the particular stock item is 12,000 won, a value indicating 1000 is recorded in the unit field 1321, and 12 is recorded in the current value field 1324. Compared to other information, the variation width 1313 may have a negative value, and thus has a field 505 expressed as an encoded 4-byte value (intsilo: integer signed long). 4 bytes are allocated to the change range field 1323 compared to the previous day so that the change range from the previous day can be recorded as an absolute value regardless of the unit designated by the unit field 1321. In contrast, the other fields 1324, 1325, and 1326 are designated as unsigned little byte values (intunli: Integer unsigned little) because the range to be expressed is relatively small due to the field indicating the unit.

The stock price component 1303 of the trade volume information constructed according to the syntax illustrated in FIG. 5L first includes a code 1331 of the stock and also accumulates today's trade volume 1333 according to each bit value of the selector 1332.

According to another embodiment of the present invention, each interest rate type according to a predetermined order in the interest rate data field 902 is not transmitted to the index type unit 1711 without transmitting an index information unit having a code for specifying an interest rate type. The interest rates for CDs, government bonds, calls, etc.) can be recorded sequentially in 2 byte increments. In addition, of course, interest rates for each type may be recorded according to other formats.

Stock-related information configured in the manner described above may be provided muxed to other broadcast signals, for example, digital TV broadcast signals.

FIG. 18 illustrates a configuration of a navigation terminal according to an embodiment of the present invention mounted on a vehicle or the like for receiving a TPEG application signal including stock-related information and traffic information transmitted from the traffic information providing server 110. It is.

The terminal of FIG. 18 includes a tuner 11 for outputting a modulated application signal by tuning a signal band of a TPEG application, and a demodulator for demodulating the modulated application signal and outputting a sequence of transmission frames as illustrated in FIG. 12), the TPEG decoder 13 for decoding each demodulated transmission frame to obtain various application information, and the GPS module for receiving a satellite signal transmitted from a plurality of low-orbit satellites to determine the current position (longitude, latitude, and altitude). 18, the storage means 14 for storing various graphic information, the input unit 19 for receiving the user's input, the communication module 17 for performing an interface and communication protocol with the wired or wireless network, the user's input The controller 15 controls the screen output based on the current location and the acquired application information. Lee (15a), is a driving signal of the LCD panel (16a), and to display graphics for video display comprises an LCD driver (16b) which is applied to the LCD panel (16a). The input unit 19 may be an interface provided on the LCD panel 16a, for example, a touch screen. The storage means 14 may be provided with an electronic map in which each link on the road, lane information of the link, and information on a node are stored.

The tuner 11 tunes a signal transmitted from the traffic information server 110, and the demodulator 12 demodulates the tuned signal in a predetermined manner and outputs it in a transmission frame sequence. Then, the TPEG decoder 13 extracts each transport frame from the input transport frame sequence, extracts the TPEG message in each service component frame included in the transport frame, decodes it, and stores it in the memory 15a. do. In another embodiment according to the present invention, only the service component frame carrying the application information corresponding to the application service designated by the controller 15 without decoding all the service component frames in the transmission frame is extracted and the TPEG in the component frame is extracted. You can also decode the message. To this end, the TPEG decoder 13 needs to know the association value between the identifier (AID) of the application service and the SCID added to the front end of each service component frame in the transport frame. From the corresponding information of each AID and the assigned SCID contained in the service table guide obtained by decoding the data in the service component frame (which is called SNI (Service & Network Information) data) having the SCID assigned to 0 in the frame. Able to know. When an application service is specified, that is, when an AID is specified, the SCID corresponding to the AID is identified, the service component frame in which the SCID is transposed is identified, only the frame is extracted, and the TPEG message in the frame is decoded. It is stored in the memory 15a.

The decoded TPEG content 15b stored in the memory 15a stores not only traffic information but also stock related information described above. Since the present invention relates to a technology for providing stock-related information, description of traffic information is omitted. The content decoded by the TPEG decoder 13 includes stock related information provided according to the scheme described with reference to FIGS. 2A, 3A and 3B, and FIGS. 4 to 17. The decoded content is stored in a database according to a predetermined method between the TPEG decoder 13 and the controller 15.

Therefore, when the user requests the stock information through a specific key on the traffic information providing screen, the controller 15 switches the information display screen to the stock information screen and decodes the desired stock related information according to an additional user input. The TPEG content 15b in the database is found and displayed on the LCD panel 16a.

The user may request information that can be obtained through the bidirectional channel, if necessary. This is done when the current stock information server 100 wants the user to immediately know the information which is not provided due to the narrow broadcast signal band or is not frequently provided. In this case, the above-described server information is used, which will be described in detail below.

First, when the user requests bidirectional information (detail or professional information, etc.) of the user, the controller 15 provides a UI necessary for selecting a desired information type, and grasps information desired by the user through the provided UI. Once the desired information is known, the controller 15 constructs a query container from the information. The query container is configured according to the syntax illustrated in FIGS. 10A-10E. 19A illustrates an example of a query container that the controller 15 can configure. The combination of the query components illustrated in the drawings is merely an example and is not necessarily to be combined as illustrated, and some of the illustrated query components are excluded from the query container or newly defined query components are included in the query container. It may be.

Referring specifically to the query component illustrated in FIG. 19A produced by the controller 15, the price detail query component 1901 includes a selector 1911 and according to the bit value of the selector, the daily and interval quote components. It may include. As shown in the syntax illustrated in FIG. 10B, the selector 1911 also performs the function of specifying the content of the query (or request) as its bit value in addition to simply indicating that there is information to be followed. For example, when the least significant bit of the selector 1911 is '1', it indicates that the content to be queried (requested) is 'hourly price', and when the lower second bit is '1', the content to be queried is 'daily price' In this case, a 'segment component' for designating a time zone in a corresponding day is configured and further included according to the syntax illustrated in FIG. 10C. The interval component includes information indicating a start time 1921 and an end time 1922 of the corresponding interval. The end time 1922 may be omitted, but when the end time is omitted, the end time is determined by the receiving side (ie, the server receiving the query) as the current time.

The quote graph query component 1902 produced by the control unit 15 selects (intunti: integer unsigned tiny) a selector (1931) indicating the content to be queried (as requested), according to the syntax illustrated in FIG. 10D. There is no information added according to each bit value of the selector. The querying or requesting content when each bit of the selector 1931 is set is illustrated in FIG. 10D.

In addition, the chart analysis query component 1903 produced by the control unit 15 includes a selector 1941 indicating a query or a request content, according to the syntax illustrated in FIG. 10E, wherein each bit value of the selector is included. Also included is a value (<stk09_xx>) that indicates the interval of the requesting chart. For example, if the user requests a basic chart of 'one day', the selector 1941 is set to a value of 00000001, followed by a value representing 'one day' (for example, <stk09_01>).

After creating the query container 1900 in the manner described above, the index container 1971 is configured to configure the transport format illustrated in FIG. 19B. The index container 1971 includes an item code for specifying a specific item requesting the quote information and a value (<stk02_2>) indicating that an index type is an individual item, and other configuration methods are the stock information server 100. Is the same as the configuration method is omitted here. If there is information necessary to specifically specify the content of the query, the controller 15 may further configure necessary information as another STK component 1972.

After completing the stock event container 1962 in this manner, the control unit 15 constructs a message management container 1961 according to the syntax illustrated in FIG. 3A and transfers the message management container 1961 to the stock event container 1962. Complete the query TPEG message (1953). In front of the query TPEG message, payload data for packet transmission is added by adding access location information (URI and port information) obtained from server information contained in the decoded TPEG content (1952). Complete In addition, a packet header address 1951 for packet transmission is added to complete the packet for querying and to transmit the packet to the communication module 17. The packet header address is prepared using the IP address included in the URI and port information. The communication module 17 modulates the received transmission packet to fit the wired or wireless bidirectional communication channel to which the communication module 17 is connected, and transmits the received transmission packet to the network. In the example of FIG. 19B, the query TPEG message is shown to be included in the payload of one transport packet. In reality, the query TPEG message is divided and transmitted through a plurality of transport packets.

The TPEG message sent to the network is transmitted to the server (for example, the response server 101 of FIG. 1) designated by the server information in the broadcast TPEG message by the access position information of the front end. This server is a server capable of responding to inquiries from the terminal and shares the stock related information with the stock information server 100 together. Therefore, the response server 101 interprets the received TPEG message for the query to grasp the requested (required) content and constructs information in accordance with the identified query in the form of a TPEG message. The TPEG message configured at this time may be one of stock-related information described with reference to FIGS. 4 to 17 that fits the query. The method of configuring information corresponding to the query contents of the response server 101 into a TPEG message is the same as that of the stock information server 100.

After the response server 101 constructs a TPEG message including one or more STK components 2020 with response information corresponding to the query, as illustrated in FIG. 20, the query information is placed in front of the TPEG message. The sender address information in the header of the transport packet is copied, and a transport packet 2000 (actually a sequence of transport packets) is constructed and transmitted to the terminal of FIG. 18 through a bidirectional channel.

The transport packets of the TPEG message prepared according to the query and transmitted through the bidirectional channel are received through the communication module 17 and transmitted to the controller 15. The control unit 15 collects the payload data in the received transmission packet, completes one TPEG message, and requests the TPEG decoder 13 for decoding thereof, and the TPEG decoder 13 sends a TPEG message according to the request. Decode and store in the memory 15a.

Meanwhile, the TPEG decoder 13 updates the same information on the TPEG content db 15b in the memory 15a or ignores the decoded information according to the index version in the decoded TPEG message or decodes in the memory 15a. The TPEG content db 15b is kept as always up to date information.

When the TPEG decoder 13 receives the STK component of the link information configured as shown in FIG. 9P while decoding the received TPEG message, the TPEG decoder 13 is configured as shown in FIG. 11 with reference to the information decoded by the STK component. Further decode the data in the service component frame (the service component frame to which the decoded SCID is transposed) that carries the associated information in the received transmission frame. Application information decoded in the TPEG message having the same MID as the decoded MID in the decoded TPEG messages is stored in association with the previously decoded stock information 2101 as shown in FIG. 21.

As described above, when the stock information 2101 having the connection information 2102 is output on the LCD panel 16a by the user's request, the controller 15 stores the information indicated by the connection information 2102. The related information 2111 is also displayed on the screen.

If, in the service table guide previously decoded and stored in the memory 15a, the SCID associated with the same AID as the decoded AID is different from the decoded SCID, it is on a transport frame provided through another transport channel. Since the tuner 11 and the demodulator 12 can demodulate and demodulate other channels thereof, the associated information is obtained in the manner described above, and as illustrated in FIG. 21. If not, the information received through the STK component of the link information is ignored.

Meanwhile, the user may designate a 'stock information monitoring mode' for the terminal of FIG. 18. 'Stock Information Monitoring Mode' overlays the current display screen with or without screen switching when stock information that meets the user-specified conditions is received while performing other application services such as traffic information navigation. It is a method to display stock information that meets the conditions in the form of (overlay).

22A illustrates a process of displaying stock-related information according to an embodiment of the present invention, and FIG. 22B illustrates a signal flow exchanged between a user, a terminal, and servers according to the process.

As shown, when the user selects any one of the index, stock, exchange rate or interest rate (S2201, SF221), the controller 15 presents a window for inputting the filtering condition desired by the user (SF222). ). For example, when the user enters a 'item', a filter input window for inputting a filtering condition for display, such as "item name (or item code) = AAAA" and "selling price = XXXXX", is presented. The user can designate a desired filtering condition through the filter input window (SF223). Of course, the filtering condition may not be specified by the user.

When any one item is selected, the controller 15 sets the decoding activity of the item to the TPEG decoder 13. Then, the TPEG decoder 13 receives a TPEG message of stock information (S2202), and checks whether the received TPEG message includes the STK component carrying information on the set item (S2203). If included, the STK component (and additional components, for example, an index container) is decoded (S2204, SF224).

If there is a filtering condition set by the user (S2205), it is checked whether the information of the decoded STK component meets the filtering condition (S2210). If there is no filtering condition or the decoded information meets the filtering condition, Decoded stock-related information is stored on the memory 15a. In one embodiment according to the invention, the control unit 15 is then informed of the data storage. The controller 15 receiving the notification or monitoring whether the TPEG content 15b is updated on the memory 15a displays the stored stock related information on the LCD panel 16a (S2211, SF225). . At this time, the currently displayed screen is switched or the decoded stock related information is superimposed on the displayed screen.

When the TPEG decoder 13 decodes the STK component of the user selection item, the TPEG decoder 13 checks whether there is also an STK component of the link information in the TPEG message carrying the STK component (S2212). Decode the STK component to obtain the link information, and then use the link information to obtain related information provided through another application service in the same manner as described above (SF226) and together with the stock related information previously displayed on the screen. The control unit 15 is output on the screen under the control of the control unit 15 (S2213, SF227). The above operation continues until the user requests another item of stock related information (S2214) or requests the termination of the stock use service (S2215). If the end of the stock use service is requested, the controller 15 switches to a screen before use of the stock use service, for example, a navigation screen, if necessary.

The detailed information may be obtained and displayed through a bidirectional channel during the display process of the stock information. 23A illustrates a process of acquiring and displaying detailed information through a bidirectional channel according to an embodiment of the present invention, and FIG. 23B illustrates a signal flow exchanged between a user, a terminal, and servers according to the process. It is illustrated.

In the process illustrated in FIG. 23A, steps S2301 to S2311 (SF231 to SF235) are performed in the same manner as the corresponding steps in FIGS. 22A and 22B. If the TPEG decoder 13 displays the stock-related information (S2311, SF235) that meets the conditions set by the user, the TPEG decoder 13 also displays the STK component of the server information in the TPEG message containing the STK component including the displayed information. (S2312). If not, the controller 15 notifies that the server information exists, and also transmits the decoded server information to the controller 15. Then, the control unit 15 displays a message indicating that "additional information can be obtained in addition to the displayed information" on the LCD panel 16a (SF236) and checks whether the user requests additional information (S2313).

If there is no request for additional information within a predetermined time, the process proceeds to the next step. If there is a request for additional information and designation of additional desired information items (SF237), the controller 15 uses the received server information in the same manner as described above. In this case, a query message is constructed and transmitted through the communication module 17 (S2314, SF238). Accordingly, additional information corresponding to the query is obtained from the response server 101 (SF239). Output on the screen under control (S2315, SF240).

The above operation continues until it requests to terminate the stock use service (S2316). If the end of the stock use service is requested, the controller 15 switches to a screen before use of the stock use service, for example, a navigation screen, if necessary.

In another embodiment according to the present invention, stock related information may be broadcasted through a signal channel other than a transmission frame providing traffic information. For example, stock-related information having the information structure described with reference to FIGS. 3A and 3B and FIGS. 4 to 17 may be provided muxed with the digital TV broadcast signal. This allows stock-related information to be always obtained through the home image display device, which makes it very convenient for the modern person to know the stock-related information.

Therefore, the apparatus capable of receiving stock-related information according to the present invention can be enjoyed by the user if implemented in various image display apparatuses as well as the navigation terminal illustrated in FIG. 18.

FIG. 24 is a view illustrating an apparatus for receiving a digital TV broadcast signal, for example, a video composite apparatus capable of receiving and displaying the aforementioned stock related information on a digital TV receiver according to another embodiment of the present invention. It is also.

In the video composite apparatus of FIG. 24, the TPEG decoder 1813 performs the same function as the TPEG decoder 13 of the navigation terminal of FIG. 18, and the controller 1815 also performs a function related to providing a user of stock related information. It is the same as the function demonstrated about the control part 15. FIG. However, the control unit 1815 of FIG. 24 receives a digital TV signal and displays it to a user, and controls necessary for proper processing such as an OSD (On Screen Display) for a user's request related to output of an AV signal. Perform additional functions.

The tuner 1811 of the video composite device tunes a digital TV signal including stock related information in the above-described format, and the demodulator 1812 demodulates the tuned signal in a predetermined manner to transport a transport stream. ) Then, the demuxer 1821 collects payload data of transport packets having a set PID (Packet ID) in a transport stream, and collects the collected data for each PID into an A / V PES packet and a broadcast signal information packet. And it is composed of TPEG message and applied to each corresponding decoder. The TPEG message applied to the TPEG decoder 1813 is processed in the same manner as described above, the A / V PES packet is decoded into video and audio data by the A / V decoder 1822, and the broadcast signal information packet is SI Decoded by the service information decoder 1823. The decoded broadcast signal information is stored in the memory 1815a and provided to the user by the controller 1815 or used as reference information for selecting a broadcast channel. The selection of a broadcast channel is made by setting a PID value which the controller 1815 designates to extract to the demux 1821.

Meanwhile, the decoded stock-related information may be displayed on the LCD panel 1816a by being superimposed on the decoded and output image signal or may be displayed by screen switching. In addition, the video composite apparatus of FIG. 24 always decodes and stores stock-related information (1815b), and displays stock-related information corresponding to the request when the user requests it on the screen, or as mentioned above. In this case, the operation of the flow illustrated in FIGS. 22A and 23A may be performed under the 'stock information monitoring mode'.

In another embodiment according to the present invention, an apparatus for receiving stock-related information having an information structure described with reference to FIGS. 3A and 3B and FIGS. 4 to 17 and providing the same to a user is implemented in the form of a dedicated terminal.
